* The i-Plate (iPlate) is a filter for use on ADSL Broadband lines to improve the speed & stability of the connection. Since they're easy to install yourself, there are no costly engineer visits required. When connected to the master socket, the iPlate filters the 'bell wire' which used to be needed to make our old-fashioned analogue telephones ring. However, with today's touch-tone phones, this bell wire is now redundant and its presence in a master socket actually causes digital interference on the ADSL line.
